Nodes loaded in Portland

Shown here are the three OOI Cabled Array Primary Nodes that were installed during Phase II of the node installation work. Nodes 3A and 3B were loaded onto the TE SubCom Dependable during the port call in Portland, Oregon. PN5A was already onboard. All nodes are positioned on the aft deck and were successfully tested. Because these three nodes were deployed in deep water and are not a hazard to fishing activities, they do not have trawl-resistant frames. The nodes are connected to 900 km of fiber optic cables on the seafloor and have been operational since 2014. Credit: B. Ittig. University of Washington.
